MOP CLAMP AND HEAD.

Application filed March 9, 1921.

To all whom it may concern Be it known that I, JOSEPH G. COUCH, acitizen of the United States, residing at Bessemer, in the county ofGogebic and State of Michigan, have invented certain new and usefulImprovements in M0 Clamps and Heads, of which the followin is aspecification, reference being had to the accompanying drawings.

It is the purpose of the present invention to provide a mop clamp,wherein the clamps have cooperating teeth for engaging and holding themop in posltion, one of said clamps constitutinga head having a V-Shaped channel with hop engaging teeth therein, the other clamp beingmovable and including spaced rows of teeth straddling the first teeth,to insure holding the mop securely in position between the two clamps.

Another purpose involves the provision of a movable clamp having sidearms mounted and movable in guides of the stationary clamp, there beinga spring tensioned lever mounted on the handle of the stationar clampand being operatively engaged wit the movable clamp, for moving the same1n clamping engagement with the mop.

A still further purpose is to provide a device of this kind, which issimple, efficient and practical, and can be manufactured for arelatively low cost.

While the design and construction at present illustrated and set forthis deemed preferable, it is obvious that as a result of a reduction ofthe invention to a more practical form for commercial purposes, theinvention may be susceptible of changes, and the right to these changesis claimed, provided they are comprehended within the scope of what isclaimed.

The invention comprises further features and combination of parts, aswill be hereinafter Set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a view showing the improved mop clamp andhead constructed in accordance with the invention.

Fig. 2 is a sectional view longitudinally through the clamps, andshowing the actuating means in elevation.

Fig. 3 is a sectional view on line 3-3 of Tig. 4 discloses views of thetwo clamps in perspective, showing the movable clamp open.

p passing through the walls of g through the extremity of the reducedex- .teeth. The central part of the mop Patented July 26, 1921. SerialNo. 450,878.

Referring to the drawings, 1 designates the handle of the device, andwhich is provlded with a reduced extension 2, the extremity of whichengages a socket 3 of the stationary clamp 4, there being a rivet 5 thesocket and tension, to hold the parts together. The clamp may beconstructed in any suitable manner, preferably cast, and is providedwith a V-shaped jaw 6, which extends longituchnally of the clamp. Thewalls of this V-shaped jaw diverge, and extending from the crotch or thebottom of the space between the walls is a row of teeth 7. The ends 8 ofthe walls of the V-shaped jaw are flared outwardly and spaced, therebyforming guides, for the side arms 9 of the movable clamp 10, which movesin the direction of the crotch of the V-shaped jaw. This movable clampis provided with parallel rows of teeth 11, which straddle the teeth ofthe V-shaped clamp or jaw, so as to pierce the mop which it engagesbetween the 12 has thereby of the mop together. of the mop which is isplaced in position adjacent the V-shaped jaw or clamp, against theteeth, then the movable clamp is operated in a direction toward theV-shaped clamp or jaw, causing the parallel rows of teeth to straddlethe teeth of the V-shaped clamp, hence holding the mop securely inclamping relation between the two clamps or jaws. The guides of thestationary clamp hold the movable clamp in position relatively to thestationary clamp. The movable clamp has its arms extended and convergedtoward the handle. Movable upon the reduced extension of the handle is aring 14.- substantially of the construction shown, and pivotally mountedupon the ring 14 as at 15 are the arms 16 of the actuating lever 17 Thearms of the lever are detachably connected to the ring. The extremitiesof the extended arms of the movable clamp are hooked and are pivotallyenga ed in eyes of the lever as shown at 1 8. suitable expansion coiledspring 19 is interposed between the stationary clamp and the ring, so asto actuate the ring toward the shoulder 20 of the reduced extension.

It will be noted that the construction and arrangement of the lever andits pivotal a tape 13 extending about the same, holding the strands Thecentral portion engaged by the tape connections with the ring and thearms of the movable clamp are such that when the lever is moved to aposition in contact with the handle as shown, the pivotal connectionbetween the arms of the movable clamp and the lever have been moved to aposition offset toone side of the pivot of the lever, the lever havingbeen limited in such position by contact with the handle. When the leveris in such position and as the pivots between the arms of the movableclamp and the lever have assumed positions to one side of thelongitudinal center of the handle, the

coiled spring is tending to expand, and is therefore holding the leverin contact with the handle, thereby clamping the movable clamp againstthe mop.

7 The invention having been set forth, what is claimed as being usefulis:

'1. In a device-for the purpose indicated, a stationary mop clampingjaw, a handle therefor, said clamping'jaw having a V- shaped channelprovided with a longitudinal arrangement of teeth in its crotch, a

movable jaw opposing the V-shaped channel of the stationary jaw andhaving parallel rows of teeth for straddling the teeth of the stationaryjaw for clamping the mop therebetween and means for holding the movablejaw in clamping position with the stationary jaw.

52. In a device for the purpose indicated, a stationary mop clamping jawhaving a channel provided with a longitudinally arranged row of teethsubstantially centrally therein, a movable clamping jaw in parallelopposed relation to the channel and provided with parallel rows ofteeth, adapted to substantially straddle the first row of teeth, forclamping a mop between the teeth, a handle for the stationary clamp, andmeans mounted on the handle and operatively connected to the movableclamp, for moving it toward and in clamping engagement with the mop.

In testimony whereof I hereunto allix my signature.
